1.

The product is factory calibrated at 2.5 V. The operational power supply range is from 2.16 V to 3.6 V.

2.

Typical specifications are not guaranteed

3.

Verified by wafer level test and measurement of initial offset and sensitivity

4.

Typical zero-

g level offset value after MSL3 preconditioning

5.

Offset can be eliminated by enabling the built-in high pass filter

6.

The sign of “Self-test output change” is defined by CTRL_REG4 STsign bit (

Table 28), for all axes.

7.

Self-test output changes with the power supply. “Self-test output change” is defined as

8.

Output data reach 99% of final value after 1/ODR+ 1 ms when enabling self-test mode, due to device filtering
